Only Microsoft shills (who secretly run Windows XP) are sowing this kind of disinformation, in my experience

Seriously now, I know no one who currently has Vista installed in his computer, and out of those who I know that have tried it (both friends and co-workers) not a single person liked it (let alone keeping it installed).

It's just a sample that doesn't represent an universal fact, but stating that it doesn't happen just means being in denial.
